What is the Weidmüller Surge Protection Box 2975590000?
The Weidmüller 2975590000 is a DC string combiner box with integrated Type 1+2 surge protection. It combines up to 8 string inputs into 4 string outputs and protects the DC side of a PV system from lightning and switching overvoltages.
Which PV systems is the box suitable for?
The box is designed for systems with up to 1100 V DC system voltage and 45 A rated current per string, covering up to 4 MPP trackers. With 8 string inputs, it is suitable for medium to large roof and open-field installations.
What surge protection does the box offer?
A combined DC surge arrestor of type 1+2 is installed. It protects against direct and nearby lightning strikes (Type 1) as well as transient switching overvoltages (Type 2), thus protecting the string wiring and the downstream inverter.
Are string fuses or string monitoring included?
No. This version is without string fuses and without integrated string monitoring. It focuses on combining the strings and Type 1+2 surge protection.
Is the box suitable for outdoor use and cold locations?
Yes. The housing achieves IP65 protection, making it dust-tight and jet-proof. The operating range starts at -40 °C, which means the box is also suitable for alpine and very cold locations in Austria.
